    • Backscatter Protocols and Energy-Efficient Computing for RF-Powered Devices 

      Buettner, Michael (2013-02-25)
      RF-powered computers operate using energy they harvest from radio frequency (RF) signals. Compared to battery powered devices, they have the advantages of being small and long-lived as they do not need to carry an onboard ...
    • Bayesian Computation and Optimal Decision Making in Primate Brains 

      Huang, Yanping
      This dissertation investigates the computational principles underlying the brains’ remarkable capacity to perceive, learn and act in environments of constantly varying uncertainty. Bayesian probability theory has suggested ...
    • Better Education Through Improved Reinforcement Learning 

      Mandel, Travis Scott
      When a new student comes to play an educational game, how can we determine what content to give them such that they learn as much as possible? When a frustrated customer calls in to a helpline, how can we determine what ...
    • Brains in the Wild: Machine learning for naturalistic, long-term neural and video recordings 

      Wang, Xin Ru Ru
      Developing useful interfaces between brains and machines is a grand challenge of neuroengineering. An effective interface has the capacity to not only interpret neural signals, but it needs to be practical, robust and work ...
    • Building and Accelerating a Declarative Platform for Machine Learning Model Serving 

      Lu, Yao
      Artificial intelligence has become the topic of the current and next decade. Numerous AI-related applications in computer vision, natural language processing and audio are deployed to change people's lives. Building effective ...
    • Building Behavioral Experimentation Engines 

      Liu, Yun-En
      Human behavior is an incredibly complex topic, given the variation between individuals and the many ways we can be influenced by our environment. This complexity, combined with the difficulty and expense of running experiments ...
    • The cache coherence problem in shared-memory multiprocessors 

      Archibald, James K (1987)
      Shared-memory multiprocessors offer increased computational power and the programmability of the shared-memory model. However, sharing memory between processors leads to contention which delays memory accesses. Adding a ...
    • Censorship Resistant Web Applications 

      Scott, Will
      Of the countless individuals around the world confronted by Internet censorship every day, only a small fraction are successful in reaching their destinations. This is a failing of the censorship circumvention community. ...
    • Characterizing and Improving Web Page Load Times 

      Wang, Xiao
      Web page load time (PLT) is a key performance metric that many techniques aim to improve. PLT is much slower than lower-level latencies, but the reason was not well understood. This dissertation first characterizes theWeb ...
    • Cluster analysis of gene expression data 

      Yeung, Ka Yee (2001)
      The invention of DNA microarrays allows us to study simultaneous variations of genes at the genome-wide scale. A typical gene expression data set consists of thousands or even tens of thousands of genes, and a few dozens ...
    • Computational Curation of Open Science Data 

      Grechkin, Maxim
      Rapid advances in data collection, storage and processing technologies are driving a new, data-driven paradigm in science. In the life sciences, progress is driven by plummeting genome sequencing costs, opening up new ...
    • Computational Generation of Terrestrial Animal Locomotion 

      Wampler, Kevin (2013-04-17)
      While the animation of humans is a well established topic in computer graphics, the animation of animals remains far less explored. Part of this is because in contrast to the wealth of easily obtainable motion data for ...
    • Cooperative caching in local-area and wide-area networks 

      Voelker, Geoffrey Michael, 1970- (2000)
      This dissertation extends cooperative caching systems in three new directions: (1) I study the performance tradeoffs of using load balancing techniques to reduce the contention of remote page requests at memory servers, ...
    • CoSolve: A Novel System for Engaging Users in Collaborative Problem-Solving 

      Fan, Sandra Benxin (2013-07-23)
      In an increasingly connected world, there are ever more opportunities for online collaboration. As the potential for more collaborators grows, so does the complexity of such communications. Problem solving, already a ...
    • Creating animation for presentations 

      Zongker, Douglas, 1976- (2003)
      In recent years the use of computer-generated slides to accompany live presentation has become increasingly common. There is a potential for using computer graphics to increase the effectiveness of this type of presentation. ...
    • Cross-Stack Co-Design for Efficient and Adaptable Hardware Acceleration 

      Moreau, Thierry Jean
      Hardware accelerators are becoming more critical than ever in scaling the capabilities of computer systems in a post-Dennard scaling computing landscape. As abstractions like ISAs and intermediate representations are ...
    • Data Structure Synthesis 

      Loncaric, Calvin Alexander
      Data structures are integral to software. Many programs require custom application-specific data structures more complicated than those found in standard libraries. Implementing and maintaining application-specific data ...
    • Data-driven Approaches for Personalized Head Reconstruction 

      Liang, Shu
      Personalized 3D face reconstruction has produced exciting results over the past few years. However, traditional methods usually require complicated setups or controlled environments to get the detailed shape of a person's ...
    • Decentralized object finding using forwarding address 

      Fowler, Robert Joseph (1985)
      A problem that must be solved in designing a large distributed computing system is ensuring that processors can "find" all of the "objects" that they have the right to access. To avoid the potential reliability problems ...
    • Design and Control of an Anthropomorphic Robotic Hand: Learning Advantages From the Human Body & Brain 

      Xu, Zhe
      According to the cortical homunculus, our hand function requires over one quarter of the brain power allocated for the whole body's motor/sensory activities. The evolutionary role of the human hand is more than just being ...
